Photoactivatable (alternatively, photoremovable, photoreleasable, or photocleavable)
protecting groups (PPGs), also known as caged or photocaged compounds, are used to …

Photocages are light-sensitive chemical protecting groups that provide external control over
when, where, and how much of a biological substrate is activated in cells using targeted light …

Photocages are light-sensitive chemical protecting groups that give investigators control
over activation of biomolecules using targeted light irradiation. A compelling application of …

Visible-light triggered quinone trimethyl locks are reported as a general design for long-
wavelength photoremovable protecting groups for alcohols and amines. Intramolecular …

A solvent-controlled regioselective rearrangement reaction of spiroindane-1, 3-diones with a
leaving group has been developed. In acetonitrile solvent, the spiroindane-1, 3-diones 3 …

A photocatalytic active alkyne generation reaction was developed using cyclopropenone as
a starting reagent. Visible light-responsive photocatalysts induced cyclopropenone …

A photoreleasable protecting group activated by sequential absorption of two visible
photons is designed, synthesized, and tested. Specifically, an anthraquinone-based …

Abstract “Tandem” uncaging systems, in which a photolabile protecting group (PPG) is
sensitized by an energy‐harvesting antenna, may increase the photosensitivity of PPGs by …

A cascade reaction involving arynes and 5-ethoxyoxazoles has been developed toward the
synthesis of 9-alkyl/aryl tritylones. 5-Ethoxyoxazoles undergo a [4+ 2] cycloaddition reaction …

Acetoxy-1, 2, 2-tri (aryl) ethanone (1) is a novel and visual release-and-report system that
contains the photochromic diarylethylene function attached to the photocage …
